having trouble with mach3 with cutter comp taking affect,i am using tool 1 with cutter radius in tool table (R.187 IN TOOL DIAMETER)
on the main screen shows tool 1 and shows cutter radius but when running program tool goes to center line of cutter
and does not compensate for tool radius.

example program milling inside pocket

G17 G20 G40 G80 G90
T1M6(.375 endmill)
G0 G90 G54 X2.0 Y2.0 G43 H1 Z-1.0 S3000 M3
Z.1
G1 Z-1.25 F30.
G42 D31 Y2.5
X2.5
Y1.5
X1.5
Y2.5
X2.3
G40 Y2.0
G0 Z1.0
G53 Z0
M30

The D parameter should reflect the tool number.

Try D1

D is the tool # who'd diameter you're using for the comp.
